U.S. President Donald Trump's son-in-law and senior White House adviser, Jared Kushner, has used a personal email account to discuss official administration business.

Kushner's lawyer, Abbe Lowell, said in a statement Sunday that Kushner received or replied to fewer than 100 messages using that account between January and August.

"These usually forwarded news articles or political commentary and most often occurred when someone initiated the exchange by sending an email to his personal rather than his White House address," Lowell said. "All non-personal emails were forwarded to his official address and all have been preserved in any event."

Under U.S. law, correspondence and other documents created or received by the president, the president's staff or anyone whose job is to advise or assist the president must be saved.

Trump has been sharply critical of Hillary Clinton, his opponent in last year's presidential race, for her use of a private email system for official business when she served as secretary of state.

美國總統川普的女婿、白宮高級顧問庫什納曾使用私人電子郵件賬戶處理白宮事務。

庫什納的律師洛維爾星期天在一份聲明中說，庫什納在今年1月至8月間用一個私人電子郵件信箱收發了不到100封電子郵件。

洛維爾說：“這些郵件通常是轉發的資訊文章或政治評論，而且大多是別人發起的，把電子郵件發送到了庫什納的私人電郵信箱而不是他的白宮電郵地址。所有的非個人電郵都轉發到了他的白宮電郵地址，而且都有備份。”

根據美國法律，總統、總統工作人員、總統顧問和助理收發的通信和文件都必須保存。

川普本人曾強烈批評他去年的總統競選對手希拉里·克林頓在擔任國務卿期間用私人電郵處理公務。
